Has anyone installed one of these themselves?
The dealer wants to charge me $250 for an install and even the guy at the parts counter is telling me to self install.
Couple questions.
Does each mustang have a unique PCM #? Apparently this is needed and I need to take apart a couple items in the engine to get to it.
And, really stupid novice question, but which cable is the batter ground cable? Black one right? This needs disconnecting to get to the PCM #.
I have read that disconnecting the battery can reset your engine's computer and mess up some of the programming. Any truth to that?
Thanks in advance for any advice
